Term 3 has just flown by! In 7AG Maths class we managed to cover three topics in a very short amount of time with a big focus on mensuration.
One of the more complex calculations students needed to master was finding the total surface area of various 3D shapes.
This can be particularly difficult when curved surfaces are involved. In order to help students visualise this idea, they made models of 3D shapes that could be flattened out into a two-dimensional net of the shape.
This helped solidify the link between the circumference or perimeter of the base area being equal to the length of the lateral sides of a prism or cylinder.
Students could use their models while thinking about the best way to find the total surface area of several common 3D shapes.
